- I think that the first published article about CATCH and THROW was by
- Klaus Schliesik (sp?) at the ForML conference back in '83 or '84. It
- was new technology then, but it is hardly new technology now. In fact,
- it wasn't all *that* new then. At the same conference, Don Colburn
- presented a paper on the related, but far more sophisticated
- exception-trapping mechanism used by Creative Solutions' Forth systems.

-
- It is also (with all due respect to the overworked and underpaid TC
- members) one of the only things in dpANS that I feel was badly misdesigned.

-
- Not only that, but this type of memory management has a *long* history
- in the field of general programming and language design. It may be
- somewhat new to Forth (and perhaps even hard to implement on 8-bit
- microprocessors), but it is hardly "invented technology". :-)
